Thinking about Cognition again, I find Rose highly suspicious. There are several hints that point to this:
1. Extreme accuracy in nurturing Cognitive abilities
I don't see how she's able to do this unless her Cognitive talent is to an A+ skill in teaching. Most likely, she herself has wide ranging Cognitive abilities. Only someone with such abilities would be able to mentor both Cordelia and Erica on controlling and expanding their Cognition talents within the spans of a few sessions on the couch. Either that or she must be involved in a Psion Group that have documented their shared experiences over decades.
2. Cordelia post-release
Currently, what happened to Cordelia after being released by the police and present time is left for Ep4. Presumably, she must have gone after Max's killer and managed to subdue him not long after a certain incident. What's left unsaid, though more than likely to happen would be more sessions with 'Rose'. I'm sure that during these sessions, Cordelia would have mentioned Erica many times. For 'Rose' to just conveniently forget to tell Erica about Cordelia means that Rose is hiding something.
Further, wouldn't have Rose continued to keep in touch with Cordelia? Since she has some knowledge of cases in Ep1-2 from both John and Erica and was asked to help out with the La Pendu and some other matters, it's hard to see how she's not involved in the whole mess. In fact, isn't it funny that the hint system not puts Rose in the driving wheel? How could she know so much, if she was an innocent?
3. Encouraging Erica to stay at the Enthon Towers
Rose specifically encouraged Erica to stay at Enthon Towers saying that John was in danger. Was this true? And how would she know unless she either had Cognitive powers of her own or was fully aware of how dangerous Cordelia had become?
Just some thoughts and speculations
